Expect a few USB 3.0 devices in time for Christmas

NEC Electronics has introduced the world’s first host controller for the SuperSpeed USB 3.0 standard, which can transfer up to 5 gigabits per second when paired with a USB 3.0 device. Host controllers are used to connect devices external to a computer system, such as Universal Serial Bus devices, SATA and IDE drives, and Ethernet connections. Typically, a host controller is either built into the southbridge of a chipset or connected to it.

The µPD720200 host controller is expected to be used primarily on motherboards, LCD monitors, televisions, and other consumer electronic devices. Large quantities of data are being created daily, and the first consumer devices using the new standard are expected to be high resolution digital cameras and video camcorders.

A new generation of external hard drives and USB flash drives is also expected to arrive quickly to take advantage of the 10x increase in transfer speeds. USB 3.0 devices will be backward compatible with host controllers using USB 2.0, 1.1 and 1.0 versions of the USB standard. By the end of 2011, USB 3.0 will become the new standard for all USB devices as production ramps up and costs fall. Everything from cell phones to printers will use the new standard.

Samples of the µPD720200 host controller are scheduled to be available in June 2009 at US$15 each, and will include free Windows device driver software. Monthly production is expected to reach approximately 1 million units during September 2009. NEC claims its USB experience will help its production ramp, as they've shipped 161 million USB devices as of March 2009.

NEC has been a member of the USB Implementers Forum since 1996, and launched the world's first USB 2.0 compliant host controller chip in 2000. NEC Electronics plans to exhibit the µPD720200 USB 3.0 host controller at its booth during the SuperSpeed USB Developers Conference in Tokyo later this week.

Let me clarify multiple things:

1. USBs current 480Mbps claim is completely false. Even at its theoretical best, that is only 60MB/s, and in reality it is always much less.

2. USB devices all share the same chunk of bandwidth. The more bandwidth, the better, no matter what.

3. This is the first controller, so expect USB 3.0 peripherals soon. Giant, fast external hard drives, giant (and fast) flash drives, external video cards (?), etc.

More speed opens more possibilities. In the tech world, saying "so what do we need X for" makes you look very short-sighted.

1. Yes 480M b /s is less than 60M B /s (51 in actual fact) that does NOT make the claim false.

8b/B => 60MB/S is correct. In claiming that it is actually 51MB/S, you are making his point. In practice, I would think that the overhead is even greater than that though... I've never gotten over 30MB/S through a USB 2.0 interface.
